A reliable and properly installed sewer connection is crucial for any property, whether it’s a new build or an existing home needing an upgrade. In the UK, strict regulations govern how properties connect to public sewers, ensuring safety, hygiene, and environmental compliance. If you’re wondering whether you need a sewer connection and how the process works, this guide will walk you through everything you need to know.
What is a Sewer Connection?
A sewer connection is the link between your property’s drainage system and the main public sewer network. If your property isn’t already connected, you may need to install a new connection or upgrade an existing one. This is especially important for new developments, property extensions, and cases where a private drainage system (such as a septic tank) is no longer sufficient or compliant.
When Do You Need a Sewer Connection?

You might require a sewer connection in the following situations:
- New Builds & Property Extensions – All new homes and commercial developments require proper drainage, which often includes a connection to the main sewer.
- Replacing Septic Tanks or Private Drainage Systems – If your existing private drainage system is failing or does not meet current environmental regulations, you may need to switch to a public sewer.
- Shared Drainage Issues – If your property shares a drainage system with others and it’s no longer effective, an independent sewer connection might be the solution.
- Public Sewer Now Available – If your property was previously too remote to connect to the mains but a public sewer has since been extended to your area, you may be required to connect.
Step-by-Step Process for Getting a Sewer Connection
If you need to connect to a public sewer, here’s what to expect:
Step 1: Determine If a Connection is Possible

The first step is to check whether your property is close enough to a public sewer for connection. This information can be obtained from your local water authority (e.g., Thames Water, Anglian Water, or Severn Trent Water, depending on your region).
Step 2: Apply for a Sewer Connection

In the UK, you must apply for permission to connect to the public sewer through your local water authority. This is known as a Section 106 application, as per the Water Industry Act 1991. Your application should include:
- Site location and drainage plans
- Details of your proposed connection
- Risk assessments and method statements (if required)
Approval can take several weeks, so it’s important to plan ahead.
Step 3: Hire a Specialist Drainage Company

Once you have permission, you’ll need an experienced drainage specialist to carry out the work. Not all contractors are approved to perform sewer connections, so it’s essential to hire a company certified to work on public sewers and highways.
Step 4: Carry Out the Connection Work

Your drainage contractor will carry out the necessary work, which may include:
- Excavating to access the sewer main
- Installing the necessary pipework
- Ensuring compliance with local regulations and safety standards
Some sewer connections may require a road or pavement excavation, in which case additional permissions from the local council will be needed.
Step 5: Inspection and Approval

Once the connection is complete, your local water authority will need to inspect and approve the work before the connection is fully operational. This ensures that everything meets UK drainage and environmental standards.
